Title: Closure:anti-trap system
Inventor: HARDING PIERS SEBASTIAN
IPC: E05F15/00
Filed: 1996-11-28
Abstract: To prevent fingers being trapped by vehicle window 11 rising towards sealing channel 21, a force applied by the fingers along channel wall 22 causes seal region 36 to act on active zone 63 of force sensing resistor 61 to stop and reverse the window. A force applied along wall 23 rocks base member 41 on its surface 43 so that region 50 of the member acts on active zone 63. If window 11 itself enters the channel it abuts channel web 24 without activating zone 63 of resistor 61. The system may used with other closures.

Title: Digital audio recording apparatus
Inventor: YOSHIZAKI ISAO
IPC: G11B27/30
Filed: 1997-04-16
Abstract: In a control unit (6, figure 1), when a digital input audio signal level (La) is equal to and beyond the first given level (L1) at a first time (t1), a delay counter (6a) starts the counting operation, and when the digital audio signal level (La) is equal to and beyond the second given level (L2) at a second time (t2), an inherent delay time (T R ) is obtained by calculating the difference between the first and second times (t2-t1), which the time difference (T R ) is compared to the predetermined delay time (T D ) of a delay memory unit (7, figure 1) to obtain a time lapse ( T N =T D -T R  ), so that a start ID is recorded at a third time (t4) at the end of the time lapse (T N ) after the second time (t2), and thus the start ID signal is recorded at an appropriate position in coincidence with the starting head of the digital audio signal, realizing a high speed search thereof without an omission of a head portion of the digital audio signal when the digital audio signal is reproduced.

Title: Video error/distortion checker
Inventor: ELKIND BOB
IPC: H04N17/00
Filed: 1997-04-21
Abstract: A video error/distortion checker generates (at 14) a difference signal from an input repetitive digital signal and a reference data signal corresponding to the input repetitive digital signal. The difference signal is compared (at 20, 22) with maximum and minimum threshold values to generate an error signal when the difference signal exceeds either threshold value. The difference signal also is used to generate a running range value that is compared (at 34) with a total range value to produce the error signal when during one iteration of the repetitive digital signal the difference signal exceeds a specified range defined by the total range value.

Title: Multi-cycle circulating sub
Inventor: MCGARIAN BRUCE HERMANN FORSYTH
IPC: E21B23/00
Filed: 1997-06-11
Abstract: The invention relates to circulating subs for use in wellbores, particularly but not exclusively to circulating subs used during downhole drilling operations. The apparatus of the present invention is characterised by controlling means for controlling the movement of a sleeve 52 between first (closed) and second (open) positions; the controlling means comprising: a control member 24 slidably mounted in a body 4 and moveable by fluid pressure in the body 4 in a first axial direction relative to the body 4; a spring 38 biasing the control member 24 in an opposite axial direction of the body 4; a pin 48 secured to one of the body 4 and the control member 24; and a control groove 32 in which a portion of the pin 48 is received formed in the other of the body 4 and the control member 24, the control groove 32 being shaped to limit axial displacement of the control member 24 in response to pressure variations in the body 4 such that only after a predetermined number of movements of the control member 24 to a first limit position is the control member 24 able to move to a second limit position to displace the sleeve 52 into the second position of the sleeve 52. The present apparatus thereby has the advantage over the prior art of being reliable and convenient to use, and compatible with the use of wireline or coil tubing tools. The apparatus may also be reset many times whilst remaining in a downhole position and is therefore less time consuming and less expensive to use than the prior art.
Patent GB-2315506-A (GB)
Title: Through tubing whipstock
Inventor: BRADDICK BRITT OLIVER
IPC: E21B23/01
Filed: 1997-07-11
Abstract: A through tubing whipstock assembly 10 may be set within a casing string CS after passing through the lower end of a smaller diameter tubing string TS. Once set within the casing string CS, the whipstock face 26 on whipstock body 12 may divert a rotatable bit B for cutting a window in the casing string CS. The whipstock assembly 10 includes an anchor A below the whipstock body 12 for securing the set whipstock assembly within the casing string. A hinge assembly 14 below the whipstock body 12 may be pivoted from a run-in position for passing through the tubing string to a set position for positioning the whipstock face 18 for engagement with the bit B. A wedge assembly 38 is provided at the upper end of whipstock body 12 and is also movable from a run-in position to a set position. The wedge assembly includes an outer wedge member 102 for engaging an interior wall of the casing string at a position circumferentially opposite the location where the window is to be cut, and an inner wedge member 104 slidably moveable with respect to both the outer wedge member 102 and the whipstock body 12. An elongate rod is positioned within a bore extending through the outer wedge member, the inner wedge member, and an upper portion of the whipstock body 12 when in the run-in position. The rod retains the wedge assembly in the run-in position, and is removed to allow the outer wedge member 102 and inner wedge member 104 to move to the set position. A rod extension extends through a passageway in the whipstock body 12 so that a lower end of the rod extension fits within a socket within a hinge arm to retain the hinge assembly in the run-in position. Once the rod is moved upward, the biasing force of a spring moves the rod extension out of the socket, thereby allowing the hinge assembly to pivot to its set position. The whipstock assembly is also retrievable through the tubing string.

Title: Digital signature protocol using a hash function
Inventor: VANSTONE SCOTT A
IPC: H04L9/32
Filed: 1997-10-09
Abstract: A digital signature protocol comprises generating a public key 32 from a private key 30, using an encryption key 34 to generate ciphertext 36 of a plaintext message, applying a hash function 38 to the ciphertext and generating a signature 40 incorporating the hashed ciphertext and the private key. The signature and ciphertext are transmitted 42 to a recipient 50 that verifies the received signature by applying a hash function 52 to the hashed ciphertext and uses this to recover the encryption key from the signature 54. The original message is obtained by application of the recovered encryption key to the ciphertext 56. Application to a mail system is disclosed whereby the message may be compiled into a printed bar code, applied to a data carrier and read by a recipient.

Title: Method and apparatus for detecting irregularities on or in the wall of a vessel
Inventor: BOWLING MICHAEL KEITH
IPC: G01M3/38
Filed: 1996-03-28
Abstract: A method of detecting irregularities on or in the wall of a vessel by detecting localised spatial temperature differentials on the wall surface, comprising scanning the vessel surface with a thermal imaging camera and recording the position of the or each region for which the thermal image from the camera is indicative of such a temperature differential across the region. The spatial temperature differential may be formed by bacterial growth on the vessel surface; alternatively, it may be the result of defects in the vessel wall such as thin regions or pin holes or cracks. The detection of leaks through the vessel wall may be enhanced by applying a pressure differential or a temperature differential across the vessel wall; the testing for leaks may be performed with the vessel full or empty, and from the inside or the outside.
